Understand your architecture with AWS Network Resource Map

In today's increasingly complex cloud environments, having a clear understanding of your network infrastructure is crucial for efficient management and troubleshooting. AWS cloud offers a powerful tool called the Network Resource Map, which allows users to visualize and comprehend their network architecture within the AWS cloud.

In this article, you'll learn how the Network Resource Map provides valuable insights into your network configuration and helps you optimize your AWS cloud infrastructure.

Let's start with the basics, what is a Network Resource Map:

The Network Resource Map is a feature provided by AWS that offers a visual representation of your network infrastructure.
It presents a graphical overview of your virtual private cloud (VPC), subnets, security groups, and network traffic flows within the AWS cloud. This map provides a high-level view of your network resources, their interconnections, and the flow of data, empowering you to comprehend the complexities of your network architecture.

Where to find my resource map:

You can go to the VPC Dashboard, select the VPC and go to the Network Resource Map tab. This presents an interactive and dynamic map, where resources are represented as nodes, and the connections between them are displayed as lines.

AWS resource map will be especially useful at the beginning of your adventure in the cloud. Thanks to it, it will be easier for you to understand how the individual infrastructure elements are connected. It will be easier to understand the flow of traffic between subnets, NAT gateways, internet gateway and gateway endpoints.

You can also find a brief mention of Resource Map in my video in which I solve the problem with overlapping IP addresses using a private NAT gateway.
